[Urinary Escherichia coli infections in the rat. Significance of the study of antibody-coated bacteria].

The value of antibody coated bacteria (ACB) determinations in localizing urinary tract infections has yet to be confirmed. According, a study of ACB was carried out in rats in which either an upper or lower urinary tract infection has been experimentally induced with E. coli. Several ACB determinations were made for each animal prior to being sacrificed for pathological studies on the 7th day after inoculation. ACB were found only in those animals with parenchymatous lesions of the kidney or prostate, thus supporting the localizing value of this technique.
